The ease of typing in the contact / company and having eveyrthing infront of me with accurate contact details
nothing!I cant fault it , has everything i need.
IT is helping find emails / numbers i wouldnt be able to find elsewhere
Cognisim is an easy-to-use tool with plug-ins for Sales Navigator and LinkedIn that work very well. I find that the information is accurate and I like diamond option.
Of course, it would be amazing to have all contact info for every person but I realize that is not possible for any platform, so it would be unfair to say I dislike this. What I can say is that Cognisim has more contact info for more prospects than any competitive tool I have used in the past.
Cognism provides accurate contact information for prospective customers. What more can a salesperson ask for? This saves me time from calling wrong numbers or writing emails only to receive bouncebacks.
Cognism is incredibly helpful in contacting people who you otherwise may not realise are within your market. It helps to gain further information on firms that they may not have on Linkedin etc.
There are no downsides. Sometimes it does get annoying with the Pop-out on every page by that is easy to turn off. Sometime the information is from people's previous firms but its quick to work out.
Helping me to better develop my Business Development Pipeline and to be a lot more productive with my time.
Cognism data is always accurate and verifying requests are quick and prompt. Super reliable!
Sometimes, there is lack of information on small businesses
Finding the accurate email addresses and mobile numbers
The Cognism database helps you reach out to almost everyone. The most helpful team is always there to support you and provide you with the best customer experience.
There are not many things I dislike about Cognism. They are very professional, and the customer service is highly proactive and always willing to help.
Cognism helps every sales rep find the correct contact details of every possible prospect. It is super easy to find the email, the phone and the title of the person that you are looking to reach out.
I like how it just works, you look at a profile and bam a few seconds later you have all the contact details of the person that you would need to reach out and grab hold of their attention.
Very little, sometimes the contact details are not always correct - but that is a small price to pay.
For me, who uses cognism to get the contact details of targetted individuals within a given industry, Cognism is a game changer, I have never used a tool as efficient and intuative. I confess that I have never used it to source large banks of contacts but I know you can.
Diamond Verify data so you know you've got the right number
Sometimes the numbers are for people with the same name
Getting hold of decision makers
I really like how many filters you can choose from when you are running a search! I also love how you can jump straight to people's linked in profiles from platform
Sometimes there are no numbers or email addresses at all
It helps a lot by being able to get the correct contact details & saves a lot of time when prospecting
easy to use, very helpful for findig emails, very helpful for finding mobiles, can compile lists and export to crm / csv - accurate for verifying emails and building sequences
i dont dislike anything about it - i'm keeping on typing here because for some reason there is a character limit lol. big fan of cognism, cant speak more highly of it
latency assocaited with building camapgins and issues with verifying emails - makes life so much easier for targeting the right people plugging into sales nav to find right ppl is amazing
I like the usability of the software and how simple it is to get the extenson working
It sometimes takes a little too long for the contacts to pull over into the CRM
Helps me to easily prospect for people without spending a lot of time on it
easy to use and the details pulled are more often than not accurate.
honestly nothing to dislike so far, does the job well.
getting in touch with key decision makers is sometimes difficult - cognism makes that much easier and more frequent.
Getting propriatory information of emails, numbers ect. It will also help you nativagte ellusive accounts on LinkedIn
Some time wrong contact details, which is understandable
Getting contact information and seeing if business are trading
It's very easy to use and highly customizable. I can create and export leads, fast, and I can export them to different file types. We have used Zoominfo with similar features but Cognism gives up the ability to fine-tune our target list.
Someone times the contact information is out of date. I don't know how often databases are updated. Verifying information sources before adding it to the database.
More accurate contact information. Better filter options and exporting capabilities. Being able to identify our ICP and the right POC leads to better conversation starters and a better demo schedule.
Cognism really helps with data to prospect and easy to use list building benefits
Sometimes the data is not accurate or numbers don't exist.
Finding data to cold call and email is difficult and Cognism takes away that difficult fact finding mission.
Intuitive nature of the system in order to add and amend filters. It allows you to have access to very specific, reliable and useful data.
Occasionally, the mobile numbers are for personal mobile numbers as oppose to work numbers - however you are able flag these issues with Cognism to amend.
Cognism allows you to flag up when the data is inaccurate and they will replace and review the data.
We like Cognism because it has been signed off by our legal team as GDPR complaint. Cognism gives us great data and helps us build outbound marketing campaigns with additional mobile contact details, which is gold dust for us.
Its not cheap, but you get what you pay for and the alternatives are nowhere near as good.
Cognism is supporting us with data to grow our business in certain regions and sectors. By giving us mobile contact details, which are legally obtained, it allows us to go directly to the best contacts without any problems.
What I liked about Cogism is the possibility of generating many qualified contacts with their email address and phone number. Thanks to the filters we can do efficient searches for our commercial prospection and mappings account
There’s really nothing I didn’t like. The tool is intuitive and powerful
Cognism allows me to have visibility on the accounts I want to prospect & gives me the necessary information to be more effective
The datas are quite up to grade. it's user friendly
the export data is not user friendly. need improve
It' a good solution to know new prospects and contacts for my business. Good filters and selections.
Easy to use, especially the Linkedin plug in. Hands down the best platform I've used for UK-based contact data.
Having to log back in occasionally, other than that nothing
Accurate contact data, especially mobile numbers for UK based contacts
the cantact details for decision makers.
Sometimes the mobile numbers are not accurate .
getting past gatekeepers
The best feature for me is the ability to search for individuals with a selection job roles across multiple organisations simultaneously. Furthermore, the quality of contact information is outstanding.
Can be a little glitchy and laggy. I sometime got #403 errors when I was using Cognism, requiring me to contact Cognism support. This lead to time being wasted and delays. Cognism is also slow to load and run.
The #403 errors that I mentioned above, was always dealt with within 24hours of raising the ticket. Errors are not occuring as often with Cognism however it would be good to see Cognism run faster and smoother
accuracy on data sets and improvement on time management
Nothing, everything seems to work well. I got good support when i needed it to resolve issues
precise data sets that transfer directly to my crm
The ease of use. The layout and search tools are extremely easy to navigate and search for a plethora of contacts, as a discovery tool it is the best on the market. Email accuracy is also outstanding!
I struggle to think of any dislikes with Cognism, the system is so good that when 1 company out of 100 does not have email addresses I get frustrated. Other than that 10/10
Having used other similar tools in the past, I was consistently frustrated with inaccurate emails, Cognism has reduced this significantly and occurs very little.
I like the fact that mobile phone numbers are often listed in profiles as these are usually impossible to obtain.
Some of the data is out of date or can be incorrect, i.e. telephone number no longer in use, etc.
Gaining access to senior management and C-suite directors at companies
We trialled a few data platforms as part of our initial research and found the data accuracy was highest at Cognism.
The prospecting tool is mostly fine except some fields won't allow you to upload a CSV to find some individuals. I have suggested some improvements and I'm not sure whether it was put into consideration or not. Some feedback either way on that would be ideal so I know whether it's been considered for action or not.
Cognism is helping us to fill the gaps in our data by providing accurate contact details. It gives us a much higher chance of connecting with a customer and results have been better.
The GDPR-compliant and accurate data Cognism provides for us really helps shorten our sales cycles and allows us to get B2B data at the click of a button for whoever we would like to contact.
Nothing in particular. Everything was perfect
We used to find getting B2B mobile numbers and/or email addresses of clients and prospects time-consuming and difficult to find. With Cognism we can simply enter our Ideal Client Persona and within seconds Cognism has pulled up a list of companies and contacts we can target to potentially win new business! It’s so easy to use and the team love it. It’s become part of our daily workflow – the LinkedIn connector in particular is amazing!
The diamond vierification feature performed by a human being
Some small amounts of wrong numbers to unverified prospects
Finding out all the relevant info to understand how ideal the account/prospect is
Good data to start with :) Easy interface and very reactive and helpful team !
Maybe the only thing I could dislike is that you can only select 25 per 25 contacts, or page by page.
We were facing poor data when prospecting which is a waste of time in the efficiency of our BDR team. With correct data, we get the right people faster.
Very knowledgable Super useful tips Positive & funny Greats service Credit to his team Impressed with all the shortcuts
Nothing so far It's doing what I asked of it
Outreach Prospecting Accurate info To source leads Better information Easy to use Build a sales process
It is so helpful to provide me with the extra details you are unable to find online. It has really improved my role and allowed me to exceed to new levels. i am able to contact the right and most relevent people.
Absolutley nothing. It has been so useful to my everyday, that i dont know what i would do without it at this point. it is able to give me specifics of what i am looking for without doing extra work myself
It allows me to find the most relative people to the roles, give me information about the company, and the correct contact details. it has increased my business peformance
